I have been taking it for two years now, and just in the past six months have I experienced mild to moderate insomnia. I now take 50mg of DCL before I go to sleep as well as my Advair. Could this or the Albuterol be making me have a bunch of stuff run through my head? And cause me to not get enough sleep?

I don't know about the advair, but I do know that my albuterol makes me crazy.. I can never sleep within four hours of taking it so that might be your problem...

good luck!
